Why Swimming Goggles Keep Fogging Up (And How to Prevent It)

Nothing ruins a good swim like cloudy vision. Here's what's really going on — and how to fix it for good.

If you’ve ever had to stop mid-swim to clear your goggles because you suddenly couldn’t see anything — you’re not alone. It’s one of the most common frustrations for swimmers, whether you're just getting started or doing serious training.

The good news? It’s a fixable problem. But first, let’s look at what’s really happening.

So, Why Do Goggles Fog Up?

In short: condensation.

When warm, humid air (like the heat from your face and breath) hits the cooler surface of your goggles, tiny water droplets form on the inside. That’s fog — and it blocks your vision in seconds.

This tends to happen more often when:

• The anti-fog layer inside the lens has worn off

• You’ve touched or rubbed the inside (even once)

• The water is colder than your skin

• Your goggles don’t fit properly and let moisture in

• You’re swimming hard and generating body heat

It’s basically the same thing that happens to a car window on a cold morning — except more annoying when you're halfway through a swim set.

The Quick Fixes Everyone Tries

There are a few classic tricks out there. Some work a little, some not at all:

• Spit and smear: Yep, people actually do this. It works temporarily by creating a thin film inside the lens, but… gross.

• Cold water rinse: Rinsing your goggles in cool water before your swim can reduce fogging, but only for a little while.

• Anti-fog sprays or wipes: Some help, but most wear off quickly or need constant reapplication.

• Don’t touch the inside: Honestly, this one matters. Touching the inner lens is the fastest way to ruin the coating — even if you’re just wiping water out.

None of these are real solutions if you swim regularly or for long sessions.

The Long-Term Fix: Goggles That Actually Stay Clear

Here’s the truth: if you're swimming often, you need goggles that are designed to handle fogging from the start — not ones that need a hack every time you get in the water.

That’s why we developed the AquaPro – Anti-Fog Swimming Goggles.
They’re built with a reliable anti-fog coating, a waterproof seal that actually works, and a fit that stays comfortable even on longer swims.

These aren’t gimmicky goggles with short-term fixes. They’re made for people who just want to swim — clearly, comfortably, and without constantly fiddling with their gear.

How to Make Any Goggles Last Longer

Even with high-quality goggles, a bit of care goes a long way. Here’s how to avoid ruining the anti-fog layer:

• Don’t wipe the inside of the lenses — ever

• Rinse them gently with fresh water after your swim

• Let them air dry (not in direct sunlight)

• Store them in a case to protect against scratches and dust

That way, your goggles — and their anti-fog ability — last a whole lot longer.

Bottom Line

Foggy goggles can really mess with your swim. They break your focus, slow you down, and make the whole thing feel frustrating. The cause is simple. And luckily, the solution is too.

If you’re tired of swimming blind halfway through your session, it might be time for an upgrade.
